With the colour on this header pipe? New stainless headers, idle time only on a fresh build that’s only seen the dyno.
A crack? Lol.Yes, you should be worried. Indicator of your engine getting ready to melt down. Pull 15* of timing immediately and add 75% more fuel.
On a serious note, it looks like that tube has a crack in it......That would be a major concern if so.....
See Lutz thread. You're welcome.A crack? Lol.
You see a faint something so you automatically assume it's a crack even though there's not evkugh to see to make an actual determination?
I still don't get why so many people try to look at these bullshit pictures and pick out oddities they think are fuck ups when you can't even be sure it's not just the picture or lighting or a reflection. It's like the people that look at pics of engines in 480p and try to pick out tiny imperfections they think they see lol. Come on mannnnnn.
"look at that smudge/crack/whatever on the cylinder wall! Look at this! Look at that!"
"Its just a reflection."
